Rules and Procedures

General Information

Who makes the rules?

The ACBL establishes the rules and procedures for most duplicate bridge played in North America. There is an ongoing review process by which these rules and procedures are periodically revised and updated.

Do I have to know all the rules to start playing duplicate?

The short answer is no. You need to know the basic background rules of bridge , and that you should call the director as soon as anything strange happens (for instance, if your partner opens one heart and then your opponent tries to bid one diamond, you should call the director).

You also need to know a little bit about something called the alert procedure .

Familiarity with the rules can help players feel more comfortable and confident about playing bridge, and especially about alerts and director calls.

Why are there so many rules and procedures?

In duplicate, comparisons are made among results achieved by players holding the same cards and playing bridge. When something goes wrong (the cards get mixed up, or someone makes a mistake such as bidding or leading out of turn or revoking), those comparisons become unfair because the basic assumptions about the way the game works are no longer in effect. The primary purpose of the rules and procedures is to make the game as equitable as possible by attempting to prevent such irregularites and to make appropriate adjustments in the event that an irregularity has taken place.

What if the rule doesn't seem fair in a particular situation?

When the adjustment from the rules seems insufficient (as compensation to non-offenders), further redress is possible at the discretion of the director; when the adjustment seems too harsh (as penalty to offenders), however, it stands.

What is active ethics?

The principle of active ethics embodies the intent of the rules and procedures. This principle encourages players to participate fully in the effort to maintain equity.

Full disclosure

Winning is more meaningful when your opponents had all of the information to which they were entitled. Players who practice active ethics give their opponents full disclosure of partnership agreements whenever appropriate (for example, give complete answers to requests for information (when asked to explain your partner's 2NT response to your 1D opening, include not only the point range, but also whether your partner's call denies a 4-card major--don't wait for the opponent to ask exactly the right question to give that information)).

Partnership agreements

Active ethics and common sense dictate that in order to play a convention, you should fully discuss it with your partner so that you know when it applies in order to avoid the awkward situation of not knowing what your partner's bid means. You may end up with a good result because you misinterpreted your partner's bid, but it is so much more rewarding to earn your good results.

When you have a regular partnership, you may know more about your partner's bids than your opponents do; they may ask about your style, and then the principle of full disclosure applies. In addition, you should be careful that any tendencies that have developed into understandings (such as a tendency to open a four-card major in third or fourth seat) are marked on your card so that your opponents have access to all the information that you have--you are not required to adhere rigidly to the system marked on your card, but once you form habits that deviate from it, you should change the way your card is marked (so it's not unethical to open a 4-card major if your card says you never do, unless you have done so enough in the past that your partner will not be surprised to discover you do not have five).

Slow play

Long waits between rounds are usually frustrating. Actively ethical players will make an effort to catch up whenever they are behind, even when they start a round late through no fault of their own.

General courtesy

Making the game more enjoyable for everyone includes treating your opponents with respect. Active ethics encourages players to greet their opponents at the start of the round and wish them good luck at the end of the round, to compliment their opponents' bidding and play as appropriate, and to avoid doing or saying anything that is likely to upset or intimidate their opponents.
